I flew to NBO last week on 719/720 and the Airbus had Suites. 12 of them. They were what could be politely called "first generation suites" in the sense they looked like someone took the suites out of the mainfleet 777, shoved it in a microwave and left it there for 3-weeks.
It was pretty beat up, screen was smaller and squarer - but overall it wasn't bad. And as other people have rightly said, F service is fine. J looked not good at all.
